Abstract: The invention relates to a method for selecting a volume of interest in one or more digitized images. A geometric structure in the digitized image for selecting a volume of interest is defined. A segmentation of the volume of interest in the digitized image is performed and visualized. The invention further relates to an apparatus, in particular a computer for performing the methods and a computer storage device comprising machine readable and executable program instructions which comprise steps of performing the methods. The invention can be applied for modern imaging developments, such as Computed Tomography, Angiography, and Magnetic Resonance Imaging which have made possible the acquisition of volumes where a volume of interest, e.g. the whole blood vessel tree, can be accurately visualized.
